Gable Vents

The importance of gable vents is to simply and naturally vent the hot air out of your attic.  Gable vents that vent properly will add years of life to your roof and home. 

The first gable vents used by home builders were not louvered but more decorative.  The builders would leave an opening in the gable end and then use wood slats to make a decorative cover to help keep out birds.  But the decorative vent cover was still vented.  Later, about a hundred and fifty years ago, the louvered gable vent became popular since it would also keep blowing rains out of the attic.  Around a hundred years ago, screen was added to keep out smaller critters such as wasps.  Then, metal vents were introduced to prevent rot. Wooden louvers were not designed for all the sun and rain they were forced to endure.  Galvanized vents were very common in the 1950’s.  Easy to obtain and then paint them to match the home.  But there was a major rust issue determined after they are about ten years old.  Even if they were painted regularly, the welds would deteriorate and weaken the vent louvers.  Not long ago, vinyl was introduced to solve all these vent issues.  Little did contractors know, they had a worse issue.  Vinyl does not take to heat very well, and it began to crack and warp. 

We have chosen to manufacture our gable vents from coated aluminum.  Raw aluminum has two real problems.  It oxidizes from rain and sun and can’t be painted.  By using the pre-coated aluminum to make the gable vents, the aluminum has been treated for the coating to stay on.  This coating comes in any color you want to match your home. 

Some are unaware that there are actual specs for these gable vents to work correctly and last longer.  The standard life-time warranty is 50 years with most manufacturers and most do provide products to stand up to their warranty.  But some custom gable vents are not made to any specs or standards.  These quickly become a disappointment to the customer.  That is why, even if you are ordering a custom gable vent, we will marry your design and measures with the required specs to keep your warranty intact.

These louvered gable vents are manufactured in a different manor than other manufacturers.  We do not butt cut the louvers and pop rivet them into a track.  This leaves a vulnerability.  Wind provided vibration of the gable vent and the louvers can eventually work loose.  Using a rail system locks the ends of the gable louvers onto the rail backed up by a pop rivet.  This reduces the wearing on the pop rivet from the vibration and more than quadruples the life of the gable vent.

The next step is to seat the gable vent into it’s cover or flange.  We offer all four flange types to match your installation preference.  If you need to mount the gable vent inside a brick opening, the no flange has no nail fin to have to remove.  For siding installs, we have the j channel flange.  The j channel is built into the outer most of the gable vent trim allowing the siding to slide into the track.  Dealing with stucco?  The back flange is great for mounting on the wall and applying the stucco around it.  But, the most popular flange with contractors is the front flange or nail fin.  This is the most versatile gable vent option.  The vent slides into the gable wall from the outside and can be mounted in many ways.  Also, the gable vent is already trimmed out.

Another item to watch on a gable vent is the strength of the louvers.  Where others will only use one fold on the front of their louvers and no extra stiffener on the back, we call these contractor grade gable vents and we will not stretch these louvers over 24 inches.  A good, durable vent louver is our Signature Series gable vent.  It has a 4-fold on the front and a double hem on the back.  Onyx Xteriors gable vent louvers can be of any length. 

Using only top quality aluminum can make for a better gable vent.  When we say Made in USA we mean Made in USA 100%.  We check all parts and raw materials for USA proofs before using them on our gable vents. 

And 100% aluminum means that these gable vents are manufactured completely out of aluminum.  Some use a wooden frame and staple the metal louvers onto the wood.  We frown upon this cheap tactic.  Wood will warp and even rot when used in metal wrap situations such as this.  And the staples rust out to leave to fastener holding the louver.  Some companies even go lean on the amount of aluminum used in their gable vents, sacrificing quality for cheaper prices.
